Antarktyczna temperatura ulega zmianie
Antarktyczna temperatura ulega zmianie – Researchers at the University of Washington in Seattle (USA), after analyzing data from satellites observing Antarctica, came to the conclusion that Antarctica warmed by 0.5 ° C between 1957 and 2006. Scientists noticed that the temperature quickly rises to the west Antarctica. Heating the continent has an impact on rising sea levels.
Daniel Gabriel Fahrenheit – Wynalazca termometru
Daniel Gabriel Fahrenheit – 05.24.1686 was born physicist and inventor, Daniel G. Fahrenheit. He invented the mercury thermometer and developed a temperature scale, called his name. Produced thermometers, barometers and altimeters. He described the phenomenons of supercooling water and dependence of boiling water and pressure.
Najchłodniejsze miejsce układu słonecznego
Najchłodniejsze miejsce układu słonecznego – American space probe Lunar Reconnaissance Orbiter (LRO), close to the pole of the Moon, on the southwestern edge of the crater Hermite discovered the coldest place of the solar system. The temperature was -249 ° C, thus lacking 24 ° C to the point of absolute zero. Substance cooled to -273.15 ° C, or to absolute zero, has no thermal energy. It is a place which does not escape any direct sunlight.
Najgłębszy odwiert Ziemi
Najgłębszy odwiert Ziemi – For the deepest drilling on land experts believe a hole made on the Russian Kola Peninsula. Researchers began work in 1970., And already in 1984. Went down into the depths to 12 068 m. It was planned to pass through hard rock to a depth 13,5-15 km, but not proven diamond drilling tools and therefore are listed on a specially ceramic blades designed. Scientists surprised by, among others, numerous thermal springs flowing from the broken crystalline rocks on which it was assumed that they will be dry. When removing rock samples tore up under pressure, crumbling rock material, and sometimes exploded. The water temperature at the hole bottom was 220 ° C, pressure – 1,400 atmospheres.
Bakteria pod oceanicznym dnem
Bakteria pod oceanicznym dnem – American geologists from Oregon, performed in Atlantic oceanic crust (where the temperature is approx. 102 ° C) drilling to a depth of 1,391 m. Among granitic igneous rocks found relatively rich bacterial ecosystem. Bacteria feed on methane and benzene there.
Octopus has three hearts
Octopus has three hearts – Octopus is a highly intelligent cephalopod, has neurons in the tentacles, teeth, tongue, and three hearts. Octopuses also have an unusual blood color: blue. Their transport of oxygen through the blood is not based on iron, but the copper. This solution is better suited to low temperatures and low oxygen concentrations.
Copper cube in cryostat
Copper cube in cryostat – Italian researchers from the Institute of Nuclear Physics (INFN) put the copper cube with a volume of 1 m³ and 400 kg in a special cryostat designed so that extremely cool down items. This is the first cryostat, which maintains the temperature course barely above the absolute zero (0 Kelvin = -273.15 ° C). In the case of copper cube thermometer stopped just 6 milikelwinach, or 0.006 degree above absolute zero.
2014 year was the warmest
2014 year was the warmest – According to the analysis of the US National Oceanic and Atmospheric Administration (NOAA), 2014 was the warmest year since the beginning of the measurements. For the first time since 1990. Record temperature achieved without the influence of the weather phenomenon El Niño.
Temperature records – In Europe, 2014. It was the warmest year since at least 500 years. Records temperatures fell in Denmark, France, Germany, Austria, Sweden, Switzerland, Slovakia and the Czech Republic.
Camera behind back
Camera behind back – They conducted an experiment in which volunteers were sitting in a closed room, and behind them was installed camera and did not know when it is activated. Over 70% of people participating in this experiment were recorded rapid heart rate, and increased body temperature, when they were under observation. Some neurologists are convinced of the existence of the „third eye”. They seek it in the pineal gland, which is also in total darkness captures visual stimuli. Probably has the ability to detect the electromagnetic field – and therefore probably can receive the information in a different frequency range.
